Crate crypt_ro 

A cryptographic library providing matrix-based encryption and decryption.

This library implements a custom encryption scheme using:

• Matrix transformations with configurable size
• Key-derived shuffling operations
• Random padding and mixing operations
• URL-safe base64 encoding for text operations

Features

• Configurable matrix size for transformation blocks
• Both raw byte and text-friendly operations
• Key-based encryption/decryption
• Randomized padding for better security

Examples

Basic usage:

use crypt_ro::Cryptor;

let cryptor = Cryptor::new();
let secret = "my secret message";
let key = "strong password";

// Encrypt and decrypt text
let encrypted = cryptor.encrypt_text(secret, key).unwrap();
let decrypted = cryptor.decrypt_text(&encrypted, key).unwrap();

assert_eq!(decrypted, secret);

// Using custom matrix size
let mut cryptor = Cryptor::new();
cryptor.set_matrix(64);  // Use larger blocks
let encrypted = cryptor.encrypt_text(secret, key).unwrap();
let decrypted = cryptor.decrypt_text(&encrypted, key).unwrap();

assert_eq!(decrypted, secret);

Working with raw bytes:

use crypt_ro::Cryptor;

let cryptor = Cryptor::new();
let data = b"binary data \x01\x02\x03";
let key = "encryption key";

let encrypted = cryptor.encrypt(data, key).unwrap();
let decrypted = cryptor.decrypt(&encrypted, key).unwrap();

assert_eq!(decrypted.as_bytes(), data);
